Rolex produced a number of "Air" models during and after World War II, including the "Air-Giant", "Air-Lion", and "Air-Tiger", but it was the 1945 introduction of the Air-King that would leave a lasting mark. These were named to honor the British Royal Air Force, which were enamored with Rolex watches. At the time, the 34 mm case was considered quite large, thus the "Air-King" name.
The first Air-King references appeared in the 1940s and used various hand-winding hunter movements. This included the original Ref. 4925 (and the similar Ref. 4365 which was sometimes given other names) as well as the follow-on Ref. 4499.
The truly iconic Air-King reference, 5500, appeared in 1957. It featured all the elements we now know: A clean bezel, simple dial and markers, pencil hands, and no complications. Combined with a Oyster bracelet, the Air-King Ref. 5500 would remain a cornerstone of the company's product line for an amazing 37 years. These watches were fitted with the simple and reliable Cal. 1530 ("Super Precision") or Cal. 1520 ("Precision").
A companion model, Air-King-Date, Ref. 5700, remains the only model with any complication. It was produced from 1958 until the 1980s but is somewhat rarer than more ordinary Rolex Datejust models. A larger 35 mm Air-King for export markets, Ref. 5504, was also produced beginning in the 1950s. And a 34 mm Air-King, Ref. 5520, was available in some markets from 1974 to 1986.
In 1989, Rolex introduced a new Air-King Ref. 14000. This used the company's updated Cal. 3000 but remained the same small, simple watch. One major change was made at this time, however: The Explorer-style "3-6-9" dial was made available in addition to the traditional stick markers. An additional reference, Ref. 14010, debuted as well with a decorative engine-turned bezel, highly unusual for the Air-King line. This reference was refreshed as Ref. 14000M in 2000 with Cal. 3130 but remained mostly unchanged otherwise. Some models also featured Roman Numerals inside the stick markings.
The Air-King was updated again in 2007 as Ref. 114200. This time, most models featured Arabic numerals at 3, 6, and 9, and many had numerals at every position except 12. The old stick marker dial was no more, though one with sticks and Roman Numerals remained. Inside, Cal. 3130 brought COSC chronometer certification to the Air-King range. In addition to the decorative engine-turned bezel on Ref. 114210, a new Ref. 114234 added a fluted bezel like higher-end Rolex models. The Air-King name was discontinued in 2014, replaced by a new Oyster Perpetual model.
In 2016, Rolex re-launched the Air-King line with an all-new larger watch for modern times. The new Ref. 116900 shares its case with the Milgauss Ref. 116400, including the inner magnetic-resistant shell and comparatively massive 40 mm dimensions. The dial features the 3-6-9 numerals as well as a highly-unusual 5-10, 20-25, 35-45, 50-55 arrangement between. Unusually, only a single reference is produced, with a black dial.
